WINDO'W-PANE FASTENING.

Application filed. September 12, 1916.

To all whom it may concern:

Be it known that we, THEODORE F. OncHsLE and AUGUST D. KUMPF, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented certain new and useful Improvements in Window-Pane F astenings, whereof the following is a specification, reference being had to the accompanying drawings.

0111 invention relates to window pane fastenings such as are employed to secure panes to metal sash bars or frames. Our invention consists of a flat flexible sheet metal clip with engaging ends and an intermediate curved portion, used in combination with a pierced metal bar. It is characterized by the capacity to permanently tighten the hold of the clip upon the pane and upon the pierced metal bar by flattening the curved portion of the clip.

In the accompanying drawings, Figure I, is a sectional view of a metal sash bar and portions of two adjoining panes showing the clips as applied when the panes are put in place.

Fig. II, is a similar view of the same construction showing the curved portion of the clips flattened in order to tighten their hold upon the pane.

.Fig. III, is a perspective view of one of the clips.

The metal sash bar 1, is pierced at intervals with apertures 2, of a suitable size to receive the engagement tongue of a clip. The clip is made of comparatively thin sheet metal sufficiently flexible yet having strength and resiliency enough to maintain the pane in place prior to the flattening of the clip, as hereinafter described. The outline of the clip may vary considerably, but a convenient form is shown in. Fig. III. The clip comprises the turned down anchorage 5, of sufficient depth to be received between the sash bar and the edge of the pane; the shoulder 6; the outwardly curved portion 7, and the engagement-tongue 8,adapted to be inserted, to which the curved portion 7 extends. The tongue is within one of the apertures 2. The tongue is preferably re-curved as shown.

The anchorage 5, with the shoulder 6,

are preferably longer than the curved portion 7, giving to the anchorage portion the required leverage and at the same time admitting of the required flexibility of the curved portion 7.

In operation, the panes having been placed against the sash bar, the clips are put in place with their anchorage portions between the sash bar and the edge of the pane, and their shoulders resting against the side of the pane. In this position the resiliency of the clip permits the tongue to be engaged with the aperture 2, as shown in Fig. 1. When this has been accomplished the curved portion of the clip is pressed down and thus flattened as shown in Fig. II, driving the tongue somewhat farther through the aperture. This is because the curve of this portion is outward and wholly without a straight line connecting the edge of the shoulder with the tongue. The end of the tongue protruding from the opposite side of the aperture may be flattened against the sash bar as shown in Fig. I. In this latter position the clips exert a permanent and strong 'hold' upon the pane retaining it in place either with or without the application of a putty or cement fastening strip.

This is because the tongue protruding through and flattened against the sash bar is firmly interlocked therewith, so that no alteration of its position with relation to the bar is possible.

Having thus described our invention, we claim:

A window pane fastening comprising, in combination, a metal sash bar with an aperture therethrough, and a sheet metal fastening clip bent at one end to form a shoulder for engaging the side of the pane and an ad'- jacent anchorage portion adapted to be engaged between the sash bar and the edge of the pane by movement of said shoulder sidewise toward the pane, and at the other end shaped to form a tongue adapted to pass through and engage with the aperture in the sash bar, said shoulder and said tongue being united by an intermediate portion springing from the edge of the shoulder and curved so as to lie outside the straight line connecting the edge of the shoulder with the tongue, so that pressure upon the curved signed our names at Philadelphia, Pennsylportion to flatten it shall increase the thrust Vania, this seventh day of September 1916.
